摘要 目的分析橡胶水泥土桩复合地基在上部荷载作用下的受力性能,为研究橡胶水泥土桩复合地基奠定基础.方法通过ABAQUS有限元软件建立了桩土三维有限元模型,对不同橡胶粉掺入的橡胶水泥土桩进行计算分析,研究荷载-位移、桩身应力等各种影响其性能的曲线.结果随着橡胶粉掺量的增加,荷载-沉降曲线拐点弱化.橡胶粉掺量增大,桩间土的竖向附加应力越大.由于橡胶粉掺入增加了桩间土的水平位移,使桩间土处于三向受压状态,促进了其承载能力的发挥,调整了桩土应力比.结论合理的调配橡胶掺入比,可以在满足复合地基的沉降控制条件下,发挥桩土共同作用,改善复合地基的受力性能. The purpose of this paper is to analyze the force performance of composite foundation with rubberized cement-soil pile under the upper load,and the difference between the rubberized cement-soil pile and cement-soil pile with different rubber mixing comparatively.The method is adopted to establish a model of a three-dimensional finite element through the ABAQUS finite element software and obtain rubberized cement-soil pile′s property curves with different rubber mixing,which can be influenced by load-displac...
